Link to the code that reproduces this issue

https://github.com/danielvanc/paralel-routes-issue

To Reproduce

Either go to: https://paralel-routes-issue.vercel.app/ and skip to step 4

or follow these steps to run locally

1. install dependences with npm
2. run npm run dev
3. navigate to http://localhost:3000
4. click the link that says Click to go to SubPage
5. verify that the content of the subPage loads
6. Now refresh the page. It should show a 404

Describe the Bug

When navigating to the sub page, it shows fine but when you hit refresh / hard navigation, it then displays a 404 page.

Expected Behavior

When i hit refresh on the sub page, it should not show a 404 page but instead the actual page like it does when you navigate to it from the homepage via Click to go to SubPage.

Which browser are you using? (if relevant)

Chrome version 112.0.5615.137

I have since discovered #48090. While aware of adding a default.js/tsx, the current documentation isn't clear as to where you should put it in regards to nested routes / sub dirs, as specified in #48090.
In this instance, I feel it's necessary to followup up with #48090 by updating the documenation as necessary and then closing this once the documentation is updated. 👍🏼

However, adding a default file doesn't work inside nested route groups (such as the below)
